AIIMS 2019 Chemistry State Functions MCQ Question
Assertion : U is a state function.
Reason : T is an intensive property.
If both assertion and reason are true and reason is the correct explanation of assertion.
If both assertion and reason are true but reason is not the correct explanation of assertion.
If assertion is true but reason is false.
If both assertion and reason are false.
Correct Answer
Detailed Explanation
Option B is correct because it accurately identifies that internal energy (U) is a state function, which means it depends solely on the system's initial and final states, regardless of the path taken. This aligns with the definition of state functions in thermodynamics, where properties such as temperature and pressure are also considered state functions. Other options are not relevant as they do not provide any information or context related to the question, leaving option B as the only viable choice. Understanding that state functions are independent of the process allows students to better grasp concepts related to energy changes in chemical reactions and physical transformations.
